TEHRAN – Iran, Russia, and China are set to conduct a large-scale joint naval exercise in the northern Indian Ocean, focusing on maritime security operations and strategic military coordination.

The drill, named Security Belt-2025, will take place in early and mid-March near Iran’s southeastern Chabahar Port, involving various branches of the three nations' naval forces.  

The Chinese Defense Ministry announced the exercise on Sunday via its official Weibo account, detailing that the drill will include multiple training operations such as maritime target strikes, VBSS (visit, board, search, and seizure), damage control, and joint search and rescue missions.  

According to the ministry, the primary goal of Security Belt-2025 is to enhance military trust and strengthen practical cooperation between the participating forces. China’s People’s Liberation Army (PLA) Navy is set to deploy a destroyer and a replenishment ship for the exercise.  

A Chinese military analyst emphasized that the drill will contribute to safeguarding security in a strategically critical region, particularly one that serves as a key transit route for global energy shipments.  

Security Belt-2025 marks the fifth joint naval exercise between Iran, China, and Russia since 2019. Over the past few years, the three nations have conducted multiple military drills to reinforce regional maritime stability and safeguard international trade routes.  

In addition to countering piracy and maritime terrorism, these exercises have facilitated intelligence sharing on naval rescue operations and the exchange of tactical and operational expertise.  

In March 2024, the Iranian Navy, along with Chinese and Russian naval and airborne units, participated in the Maritime Security Belt-2024 drills. Observers from Azerbaijan, Kazakhstan, Oman, Pakistan, and South Africa attended the exercises, reflecting the growing interest in multilateral maritime cooperation.  

The joint maneuvers were designed to strengthen maritime security, bolster international trade protection, combat piracy, and enhance operational coordination among naval forces. The drills also served as a demonstration of the participants' collective commitment to global peace and stability at sea.  

As part of the upcoming exercises, the Islamic Revolution Guard Corps Navy (IRGCN) will deploy two advanced vessels: the Shahid Nazeri and the Shahid Sayyad Shirazi.  

Commissioned into the IRGC Navy in September 2016, the Shahid Nazeri is a high-speed patrol and reconnaissance vessel designed for extended operational reach. With a length of 55 meters, a width of 14 meters, and a height of 13 meters, the vessel significantly enhances the IRGCN’s maritime capabilities, extending its operational range up to 10,000 kilometers.  

The Shahid Nazeri features a specialized twin-hull (SWATH – Small Waterplane Area Twin Hull) design, providing enhanced stability in high-speed operations and rough seas. Its design ensures that it remains steady even at high speeds, reducing the risk of capsizing.  

Equipped with a helicopter landing pad, the vessel can conduct surveillance and reconnaissance missions across various maritime zones, making it a valuable asset for intelligence gathering and patrol operations.  

The Shahid Sayyad Shirazi is a newly commissioned stealth warship from the Shahid Soleimani class, officially joining the IRGC Navy in February 2024. This catamaran-style ocean-going vessel is designed for high-speed operations, with a maximum speed of 45 knots.  

Armed with a wide array of offensive and defensive missile systems, the Shahid Sayyad Shirazi is equipped with vertical-launch Nawab air defense missiles and Sayyad cruise missiles with a strike range of 700 kilometers.  

With a length of 67 meters, a width of 20 meters, and a displacement of 600 tons, the vessel is powered by four engines, enabling long-distance operations. It has an operational range of 5,500 nautical miles and is capable of carrying three missile-launching fast attack boats along with an armed combat helicopter.
